American hornbeam

Overview

American hornbeam (Carpinus caroliniana), also called blue beech, has hard, dense, nearly white wood with a fine, even grain. The Wood Database calls it difficult to work but an excellent turning wood, with excellent abrasion resistance. It is not often for sale.

Pros

• Excellent turning wood with a fine, even grain.
• Excellent resistance to wear and abrasion.
• Hard (1,780 lbf) and dense (about 785 kg/m3 dried).
• Stains, glues and finishes well.
• Pale, nearly white colour.

Cons

• Difficult to work by hand or machine because of its density and toughness.
• Poor dimensional stability for a hard wood: shrinkage is 5.7% radial and 11.4% tangential.
• Most lumber is sapwood, which is non-durable to perishable and susceptible to insects.
• Not often for sale.
• Reported to cause skin irritation.

Variants and subspecies

• American hornbeam (C. caroliniana) is the species covered.
• Not a beech: despite the name "blue beech", it is in the birch family (Betulaceae). For a true beech see American beech; see also European hornbeam and Eastern hophornbeam.

Working and finishing

The Wood Database says hornbeam is overall difficult to work because of its density and toughness, but the same density, with a fine even grain, makes an excellent turning wood. It stains, glues and finishes well.

Staining and finishing colour

Most boards are nearly white sapwood, with pale yellowish-brown heartwood that is not clearly separate. The Wood Database says it stains, glues and finishes well. Test on offcuts.

Sustainability and handling

The Wood Database reports American hornbeam as not listed in the CITES Appendices (checked 2026-09-30) or on the IUCN Red List; Wikipedia's page gives Least Concern. US-grown timber is still covered by the Lacey Act, which as amended in 2008 prohibits trade in plants and timber taken, possessed, transported or sold in violation of law (Wikipedia's summary of the Act); buy from dealers who can name the source. The Wood Database says that, although severe reactions are quite uncommon, hornbeam has been reported to cause skin irritation. The Wood Database's wood-dust article treats wood dust in general as an irritant or sensitizer and notes that fine dust can cause cumulative lung damage, so extract at the source and wear a respirator when sanding or machining.

Buying notes

The Wood Database says it is not often for sale. No retail list price was found; the Wood Database says prices should be moderate throughout its natural range.
